help needed!
i'm looking for a way to rip Data Storage CDs, ideally both as image files and as the extracted data, but i want to make sure that the output is correct.
when ripping music (with foobar2000) i had the option to use "Ripping security", which from what i understand rips the audio twice in parallel and retries until both versions match to ensure you get the correct output.
is there a program that does this but for image files and/or data? right now i'm using isobuster because that's what i have on but it doesn't seem to have anything like this.... -

But CD-ROM Mode 1 (your normal data storage CD) has additional checksums and error correction build in. So while not impossible, it's a lot harder to get a wrong read-out that is not detected.
For CD-ROM Mode 2 the safety got exchanged for more storage space... Video CDs are more likely to use that. -

Should be on any Linux Rescue system bootable from CD/USB stick, if there's no installed linux system at hand.

@anathem @kat_cal2 Depending on the failure and the state and behavior of the controller it's still worth to at least try to use ddrescue with SSDs, SD-cards, thumb-drives etc. ... at least if the device is still detected and has a non-zero size.
Otherwise either the controller is fried or it failed to read the important bits from the storage to operate. That's hardware-tools/data recovery service territory. -

I got the data off using cp -nprv. -
